genetics heritability longevity
The heritability of longevity was estimated to be 0.26 for males and 0.23 for females.
Does this imply that the other 75% is due to life choices? This doesn’t obvious to me.
No, that is not what heritability means. The other 75% is the myriad of other influences of environment, chaotic chance and life choices.
